Hi, I encountered some problems when building SuiteSparse and have applied the patch using: sudo patch -p1 < patch-SuiteSparse-Portfile and this appears to apply the patch: patching file opt/local/var/db/dports/sources/rsync.rsync.darwinports.org_dpupdate_dports/math/SuiteSparse/Portfile patching file files/patch-complex-type patching file files/patch-config patching file files/patch-disable-demos patching file files/patch-macports-metis patching file files/patch-powerpc-nanotime patching file files/patch-size_t-fix However, when I come to build octave, I do: sudo port -v install octave and get: Portfile changed since last build; discarding previous state. ---> Fetching SuiteSparse ---> patch-complex-type doesn't seem to exist in /opt/local/var/db/dports/distfiles/SuiteSparse ---> Attempting to fetch patch-complex-type from http://distfiles-od.opendarwin.org/SuiteSparse % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- 0:00:56 --:--:-- 0 Various attempts are made to find the file patch-complex-type to no avail. Can someone tell me what I need to do to build SuiteSparse? Thanks.
